Definitions

  • the present invention concerns an equipment for the recovery of oil flowing out of sub-water ground. More particularly, the invention concerns an equipment useful for recovery of oil escaping under high pressure from a damaged offshore oil well or for recovery of oil escaping from the damaged tanks of a wrecked oil tanker.
  • An object of the invention is to allow complete recovery of the oil flow, using a very " simple, lightweight and comparatively cheap equipment able to be very quickly put into operation and remain in service during all the duration of the repair operation of the damaged well or the total recovery of the oil contained.in a wrecked oil tanker, while allowing without any restriction any repair work to be performed.
  • OMPI invention comprises a tubular skirt, made of a flexible sheet material substantially impervious to liquid and gaseous hydrocarbons, said skirt being composed of an elongated tubular part and a flared part forming an extension of the elongated part, the length of the skirt being sufficient for allowing the free end of the tubular part to come in the vicinity of the water surface when the skirt is placed over a location of the water bottom from which oil is flowing upwardly, the outer edge of the flared part of the skirt being held in the vicinity of the water bottom, so that oil will be collected by the flared part of the skirt and led up towards the water surface by the tubular part of the skirt acting as a hose, and means for collecting the oil and keeping it in a restricted area of the water surface, under the form of an oil layer having a sufficient thickness to allow the oil to be pumped out.
  • the skirt is maintained in flattened and folded configuration, against the bottom of the water, with the lower edge of the flared part of the skirt tied to mooring means, around a wellhead in normal working conditions, in such a manner that the presence of the skirt does not interfere with the normal operation of the wellhead as well as with the usual survey and maintainance steps, appropriate means, comprising, for instance, inflatable or permanently inflated air bags being provided for releasing and quickly unfolding the skirt so that the free end of the tubular part is brought towards the surface of the water in case of occurence or imminent risk of blowout or oil leakage.
  • Figure 1 is a lateral section of the equipment, illustrated in its working configuration over a damaged wellhead.
  • Figure.2 is a schematical side elevation view of the lower part of the equipment, partly in section, illustra ⁇ ting its working .configuration over a wrecked oil tanker.
  • Figure 3 is a schematical side elevation view of the lower part of the equipment, partly in section, showing on one hand the skirt in flattened and folded position, around a wellhead in normal operating condition, and, on the other hand, the skirt in one early stage of unfolding after it has been released in the case of blowout or oil leakage.
  • the equipment shown in figure 1 comprises a skirt 1 which is made of a flexible material, impervious to liquid and gaseous hydrocarbons and able to withstand the chemical action of oil and salt water, said material being, for instance, a sheet of polymeric plastic or elastomeric material or a waterproof cloth.
  • the skirt 1 comprises a lower flared part la and an upper part lb acting like a hose or a chimney.
  • the outer edges of the lower part la of skirt 1 are maintained in their location, by appropriate moorings 3 such as concrete or cast-iron blocks, after the skirt has been placed over the damaged wellhead 11.
  • a bell-shaped container 2 is placed over the upper opening of the upper part lb of skirt 1 and is kept floating on the water's surface 13 by floats 4.
  • the container 2 is moored using chains 5 anchored on the water bottom 12.
  • a skirt 15 continues the lower edge of container 2.
  • said skirt is made of a flexible material such as a sheet of polymeric plastic or elastomeric material or a waterproof cloth. If necessary, for example in the case when the equipment is to be used under bad sea conditions or with strong current, the skirt 15 may be provided with stiffening organs (not shown) such as gas or liquid inflatable tubings or chambers.
  • the relative location of the bell-shaped container 2 and the upper part lb of skirt 1 is such that the opening of said upper part lb is placed inside skirt 15.
  • the upper part lb of skirt 1 is * tied to the container 2 by wires or chaims 17, or other appropriate means thus ensuring that the upper end of part lb is not displaced out of the interior of skirt 15 under the action of the waves or the currents or of the vibrations resulting from sudden changes of flow rate or pressure of the oil flow 16.
  • the oil flow 16, which is guided in the upper part lb of skirt 1 is thus led into the inner part 9 of container 2 and forms an oil layer 14.
  • the gaseous hydrocarbons are also held in the inner part 9 of container 2, above the oil layer 14.
  • a pump 6 allows the liquid hydrocarbons of the oil layer 14 to be pumped out through at least one channel 7 with or without pump attached and to be transported through channel 8 into appropriate containers, for instance in a tanker, for storage and transport.
  • the gaseous hydrocarbons are separated from an liquid fractions which may be mixed with the gas, in an appropriate chamber 10 provided with baffle-plates and then led to storage and transport gas container or to burning means (not shown) _.
  • a deflecting wall 18, having the form of an inverted f nnel with an upper central aperture 19, is preferably provided at the bottom of container 2, above the aperture 20 of the tubular upper part lb of skirt 1, in order to limit the turbulence of the oil and gas flow entering into container 2.
  • deflecting wall 18 may also be provided with a plurality of apertures, if convenient.
  • the lower flared part la of the skirt 1 can be made of sufficiently large size to be placed over and entirely cover a wrecked oil tanker 22 thus allowing collection of the flow of oil 23 escaping from the damaged tanks of the tanker.
  • the skirt 1 is placed in flattened and folded condition against the bottom 12 of the water, around a normal operating wellhead 24 with riser 25 and command and control lines 26 normally connected.
  • flared part la of skirt 1 are tied to mooring means 3, the folded and flattened tubular part la being maintained against water bottom 12 by appropriate securing means (not shown) which may be automatically or manually operated to release the part la in case of blowout or other cause or oil leakage.
  • the equipment according to the invention provides a very efficient way of avoiding oil spilling in case of blowout of offshore oil wells.
  • edges of the flared lower part la of skirt 1 can be suitably positioned, with respect to the water bottom .12., and/or of appropriate shape or, else, be provided with suitable openings or gates so as to allow an easy access to the damaged wellhead 11, for survey or repair purpose, by divers or unmanned or manned submersible.
  • the lower edge of the flared part la of skirt 1 need not, and will generally not, be placed in the immediate vicinity of the water bottom 12 and that in practice, the distance between said edge and the bottom will be amply sufficient for allowing easy access to the damaged wellhead 11 and, in any case, instant and permanent equaliza ⁇ tion of the pressure of the mass of oil gas water contained under or inside skirt" 1 with the pressure of the water outside skirt 1, even in case of strong and sudden surges of pressure of the oil and gas column escaping from wellhead 11.
  • the wall of skirt 1 can advantageou ⁇ sly be provided with a heat insulating sheath or lining.
  • a heating fluid may also be circulated in chambers or channels located in contact of the skirt walls or between these walls ' and the said lining.
  • OMPI and speedy manner and its handling and control are free of any risk.
  • the equipment can be put in operation by simply towing the skirt 1 underwater over the damaged wellhead 11 or the wrecked tanker 22 and then mooring it in its working location as shown in the drawings.
  • the bell-shaped container 2 is moored in the appropriate location with respect to the upper part la of skirt 1, for instance as shown in the drawings.
